RExpression accepts only limited input size.
The R expression actor accepts only a very limited size of input. For example,
a vector x <- 1:20000 with 20000 elements cannot be in the input.
It was mentioned that it is planed to implement a TCP/IP binding to the R platform.
Maybe this binding does not have such limitation.
The bug is severe for the bioinformatics/microarray community. Here, dataframes
and tables of very large dimensions are handled.

Some further examination indicates that the problem indicate that the problem is
in 'R' rather than the RExpression code! (More precisely, an error occurs in
RTerminal when one tried to input too large of a vector.)
The problem is that vectors are passed a strings. The strings are broken into
many lines when the vestor is long. Apparently there is a limit in RTerminal in
the length of lines that can be put together to form an R expression (text limit
appears to be 128K?)
